How do we know that true faith is a gift from God?

The origin of true saving faith is rooted in the work of the Holy Spirit in the believer's heart. As stated in Romans 12:3, God has dealt to each man a measure of faith. Additionally, 1 Corinthians 12:9 affirms, 'to another faith by the same Spirit.' This demonstrates that faith is not a mere human decision but rather an act of divine grace. Faith emerges from the spiritual rebirth, where God draws the sinner to Himself, enabling them to believe and trust in Jesus Christ for salvation.
